LMNO is a parallelogram. If NM = x + 33 and OL = 4x + 9, find the value of x and then find NM and OL.

anyanavicka [17]

Because these are on opposite sides of the parallelogram, x + 33 = 4x + 9.

This gives you x = 8; OL = 41, NM = 41.

Which can be the first step in finding the equation of the line that passes through the points 5,-4 and -1,8 in slope-intercept

zheka24 [161]

Step-by-step explanation:

First step:

Calculate a slope.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the points (5, -4) and (-1, 8). Substitute:

$m=\dfrac{8-(-4)}{-1-5}=\dfrac{12}{-6}=-2$

Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line:

$-4=-2(5)+b$

$-4=-10+b$ <em>add 10 to both sides</em>

$6=b\to b=6$

Finally:

$y=-2x+6$
